KNITTED WEB AND MAKING SAME.

Specification of Letters Patent.

.Patented Dec. 16,1913.

Application tiled April 28. 1910. -Serial No. 558,224.

To all whom t may concern:

Be it known that I, ROBERT W. Scoi'r, a citizen ot the United States, residing in Leeds Point, Atlantic county, New Jersey, have invented certain Improvements in Knitted Webs and MakingvSame, of which the following is a specication.

The object of my invention is to produce a knitted web of tine texture with the same facility as is experienced in knitting ordinary webs of coarser texture, my improved web also presenting-a novel disposition of the yarns which distinguishes it from and renders it more attractive than an ordinary knitted Web and lends itself to the brushing or gigging of one faceof the web if a fleeced surface is desired, or to the introduction ot weft threads. The improved web is also more elastic than a web in which the sinker wales cross one or more needle wales.

In the accompanying drawings-Figures 1, 2, 3 and t are exaggerated views of pieces of knitted web produced in accordance with my invention, and Fig. 5 is a diagram representing the disposition of the knitting instrumcntalities in a circular machine for producing my improved web.

The invention relates to single or plain webs having all of the stitches drawn in the same direction as distinguished from ribbed webs which have some of the stitches drawn in one direction and others in the opposite direction, the characteristic and novel features of the invention being the crossing of the sinker wales between adjoining needle walesby reason Aof the fact that the courses of stitches are staggered, successive stitches of the same yarn being produced in different coursesof the web, thus on reference to Fig. 1, it will be noted that the yarn m which produces stitches in course 2 of the wales m produces stitches in course 4 of the Wales y, the yarn m which produces stitches in course 4 of the wales producing stitches in course 6 of the wales y, and so on, the yarn 'n which produces stitches in course 3 of the Wales y producing stitches in course 5 of the wales rv, the yarn n which produces stitches in course 5 of the wales y pro ducing stitches in course 7 of the wales w, and. so on. Successive stitches in the wales and courses are also of different size, and there is a zigzag' disposition of the stitches which imparts to the web somewhat the same appearance as that of the web forining the subject of my Letters Patent No. 928,221, dated July 18, 1909. The crossing of the sinker wales on the back of the web inparts a distinctive appearance to both faces of the web and causes the .sinker wales to project to such an extent that they can be conveniently brushed to form a fleece if a flecccd back is desired.

lIt it is desired to produce a web having weft threads therein, such, for instance= as the elastic threads sometimes employed in the manufacture of surgical goods, such weft threads can be conveniently introduced before the transfer of loops from the points to the needles, as hereinafter set forth. The introduction of the weft threads can `be el'ected by means of a guide traveling in a plane between the tops ofthe retracted cylinder needles and the outer ends of the retracted dial hooks, so that it will lay its thread behind the stitches carried by the needles and on top of the loops carried by the hooks.

The fabric shown in Fig. 2 is similar to that shown in Fig. l., with the exception that the stitches are displaced only to the extent of one course, the stitches which appear in odd numbered courses in the wales m, appearing in even numbered courses in the wales y, and vice versa, all of the long stitches and all of the short stitches being in straight parallel rows. The fabric shown in Fig. 3 differs from that shown in Fig. l in having the courses staggered in adjoin ing groups of wales instead of in adjoining single Wales and consequently having the crossed sinker wales only between adjoining groups of wales. The fabric shown in Fig. 4t illustrates the same idea in connection with a web knitted in the manner shown in Fig. 2.

In producing the webs shown in Figs. 1 and 2, I use a machinehaving two sets of needles A, B. a needle of one set alternating with a needle of the other set in a needle cylinder, needle bed, or other needle carrier, as shown for instance in Fig. 5, it being understood that my invention is applicable to straight knitting machines or to circular knitting machines, and to machines using either spring beard needles or latch needles.

Each set of needles is combined with the usual devices whereby it may loe operated so as to cause it to knit, and also coperating with the needles A and ld are tvvo sets of loop receiving and transferring pins or points a and Which may be disposed at a right angle to the needles Al l2, inthe saine manner as the dial needles of'an ordinary rib knittiny machine, the points a being, how ever, by preference, in line radially with the needles ld and the points b being in line radially With the needles A, and said points being actuated so as either to receive a loop @t yarn, or to transfer said loop to the op-,

posed needle. @ne yarn is applied rst to a needle A and then to a point t throughout the series and the other yarn is applied first to a needle B and then to a point Z) throughout the series.

Supposing that both yarns have heen applied to the needles and points in the man-- ner described to forni a setting-up course, the first operation in knitting the fabric shown in Fig. l is to transfer the loops from the points a to the needles B and to knock 4over on said transferred loops the loops previously applied to said needles B. .The next yoperation is to apply fresh yarn to the needles A and points a and to knit on said needles A by knocking over `on the freshlyapplied loops of yarn the loops already on said needles. The loops are then transferred from the points b to the needles A and the stitches on the latter are knocked over on said loops, the inal operation being to apply yarn to the needles B and points and to knit on said needles B by knocking over on the fresh loops, the stitches already on the needles, these operations being repeated indefinitely.

ln knitting the fabric shown in Fig. 2, one

' yarn is first applied to the needles A. and

points a, and the other yarn is then applied to the needles i3, and points to form a setting-up course, after which the loops are transferred from the points a to the needles B and from the points 79 to the needles A, and the loops previously applied to said needles A and B are then knocked over on the transferred loops, yarn being then applied as before, the stitches on the needles then knocked over on the freshly applied loops, the loops then transferred from the hooks to the needles, the stitches on the latter knocked over on the transferred loops, and so on. ln producing the fabrics shown in Figs. 3 and d, the saine methods ofoperation are. resorted to in connection with needles and points disposed in alternating pairs instead of singly.

@ne ofthe advantages of iny invention is the provision which it affords for knitting fine gage web With the sainev facility as is non experienced in knitting coarse gage inerme knitted in the usual Way on machines of line gage. rllhe stitches which are produced from a loop of yarn laid directly upon the needles differ in size from the stitches produced by the transferred loops, thus providing for the alternation of large and small stitches in the Wales and courses of the web.

l prefer in order to facilitate production, to use a machine having a plurality of yarn feeds, so as to supply one yarn to the needles A and points a and another yarn to the needles B and points butiny improved fabric can he knitted with one and the saine yarn, hy hrst knitting a course of stitches upon the needles A With intervening loops applied to the loop holders a and then retaining said needles and loop holders' out of action, While knitting a course of stitches upon the needles B with intervening loops applied to the loop holders the transfer of loops from the loop holders to the correspending needles and the knocking-over of the stitches upon said loops being ed'ected in either of the Ways hereinbefore set forth. Although l prefer to use transfer points or pins, transferring needles, Vsuch for instance as those shown 1n my Letters Patent No. 834,763, dated October 30, 1906, may be substituted therefor, if desired.

l claim:

l. A knitted web having successively produced stitches'of a course located in different but parallel course planes in adjoining Wales, the sinker Wales crossing each other.

2. A knitted Web having successively produced stitches of a course located in different parallel course planes in adjoining needle Wales, the sinker Wales crossing each course and successive stitches in the needle Wales being composed of diderent yarns.

3. A plain knitted web having successively produced stitches of acourse located in dierent parallel course planes in adjoining needle Wales, the stitches of said p loops, and another course of stitches with v 'intervening loops alternating respectively with the stitches and loops of the rst course and drawing the loops-of one course throughthe stitches of the other.
